Why it works: Shallot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Lobster Au Gratin
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the lobster
Cut the cooked lobster in half and save the shells.
Remove the meat from the shells and place the softer portions on a plate.
Cut the white meat into smaller pieces.
Make the filling
In a saucepan, combine the lobster meat with milk thickened with flour, chopped shallot, black pepper, salt, butter, and cayenne pepper.
Warm the mixture thoroughly over low heat.
Bake and serve
Fill the lobster shells with the mixture and sprinkle with bread crumbs.
Bake in a 400°F (200°C) oven for 10 minutes.
Use a salamander or broiler to brown the top.
Serve very hot, garnished with fried parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked lobster
- Provides the main meat and flavor of the gratin.
- Milk
- Forms a creamy sauce that keeps the filling moist.
- Flour
- Thickens the milk so the filling holds together rather than running.
- Butter
- Adds richness and a silky mouthfeel to the sauce.
- Bread crumbs
- Form a crisp, golden topping that browns under heat.
The step that matters
Browning the top under the salamander or broiler. The bread crumbs brown quickly under intense direct heat, so the top can scorch before the filling is hot. Watch closely and remove it as soon as it is golden.
Swap the shallot

Fit is the average pairing score against lobster, milk, flour, pepper, butter, bread, parsley. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
